RASLog subsystem provides centralized logging mechanism. RASLog messages log system events related to configuration changes or system error conditions.
It can store 2048 external customer visible messages in total. These are forwarded to the console, to the configured syslog servers and through the SNMP traps or informs the SNMP management station.
There are four levels of severity for messages, ranging from CRITICAL to INFO. In general, the definitions are wide ranging and are to be used as general guidelines for troubleshooting. You must look at each specific error message description thoroughly before taking action.
| Severity level | Description |
|---|---|
| CRITICAL |
Critical-level messages indicate that the software has detected serious problems that cause a partial or complete failure of a subsystem if not corrected immediately; for example, a power supply failure or rise in temperature must receive immediate attention. |
| ERROR |
Error-level messages represent an error condition that does not affect overall system functionality significantly. For example, error-level messages may indicate time-outs on certain operations, failures of certain operations after retries, invalid parameters, or failure to perform a requested operation. |
| WARNING |
Warning-level messages highlight a current operating condition that must be checked or it may lead to a failure in the future. For example, a power supply failure in a redundant system relays a warning that the system is no longer operating in redundant mode unless the failed power supply is replaced or fixed. |
| INFO |
Info-level messages report the current non-error status of the system components; for example, detecting online and offline status of an interface. |
